[0021] FIGS. 1 to 4 illustrate one embodiment according to the disclosed content. FIG. 1 is a perspective view, FIG. 2 is an exploded perspective view, FIG. 3 is an operating cross-sectional view, and FIG. 4 is a view of the usage state.

[0024] Hereinafter, the components of a winding device (1) for a cable drum and their operational relationships according to a preferred embodiment of the contents disclosed with reference to FIGS. 1 to 3 will be described in detail.

[0026] First, a first support member (10) is provided. This first support member (10), together with a second support member (20) to be described later, serves to allow the cable drum (60) to be rotatably seated while being spaced apart from the ground.

[0027] This first support member (10) is installed upright on the ground, with a first base (11) provided on the bottom, a first support member (12) installed vertically in the upper center of the first base (11), and a first roller unit (13) provided on the upper part.

[0028] The first base (11) is formed in the shape of a flat plate so as to be stably supported on the ground and is fixed by the first fixing plate (121) together with the second base (21), which will be described later. This is to ensure that the spacing between the first base (11) and the second base (21) is maintained even when the cable drum (60) rotates. In addition, the aforementioned first support (12) is installed upright at the upper center and may be formed to be adjustable in length.

[0029] And the first roller unit (13) enables rotation of the rotating shaft portion (30) installed on both sides of the cable drum (60) and includes a first plate (131) provided on the first support (12), a pair of first rotating rollers (132) rotatably installed on the first plate (131) and spaced apart at a predetermined distance so that the central axis (32) of the rotating shaft portion (30), which will be described later, can be rotatably seated between them, and a first anti-detachment protector (133) provided on the first plate (131) and provided in close contact with the central axis (32) so that the central axis (32) seated on the first rotating rollers (132) does not detach during the rotation process.

[0030] The first plate (131) allows the first rotating roller (132) and the first anti-detachment guard (133) to be installed on the first support (12). The first rotating roller (132) is positioned so that two roller axes are positioned parallel to each other, and the central axis (32) is rotatably seated on the upper part of these two rollers. That is, when the central axis (32) is rotated, the rollers on both sides on which the central axis (32) is seated rotate freely, so that the cable drum (60) can be stably rotated in both directions.

[0031] The aforementioned first anti-detachment guard (133) serves to prevent the central axis (32), which is positioned on the first rotating roller (132), from detaching during rotation. It may be in the form of an elastic band or a metal piece having a curvature corresponding to the central axis (32). It is preferable that this first anti-detachment guard (133) be coated with a material having a lubricating function so that no frictional force is generated when the central axis (32) rotates.

[0033] A second support member (20) is provided at a position spaced apart from the aforementioned first support member (10) by a predetermined distance. This second support member (20) serves to allow a cable drum (60) located between the first support member (10) to be rotatably seated while spaced apart from the ground.

[0034] This second support member (20) is installed upright on the ground, with a second base (21) provided on the bottom, a second support member (22) installed vertically in the upper center of the second base (21), and a second roller unit (23) provided on the upper part.

[0035] The second base (21) is formed in the shape of a flat plate so as to be stably supported on the ground, just like the first base (11) described above, and is fixed to the first base (11) described above by a first fixing plate (121) and to the third base (41) described later by a second fixing plate (221). This is to ensure that the spacing between the first base (11), the second base (21), and the third base (41) is maintained even when the cable drum (60) rotates. In addition, the second support (22) described above is installed upright at the center of its upper section and may be formed to be adjustable in length.

[0036] And the second roller unit (23) enables rotation of the rotating shaft part (30) installed on both sides of the cable drum (60) just like the first roller unit (13) described above, and includes a second plate (231) provided on the second support (22), a pair of second rotating rollers (232) rotatably installed on the second plate (231) and spaced apart at a predetermined distance so that the central axis (32) of the rotating shaft part (30), which will be described later, can be rotatably seated between them, and a second anti-detachment guard (233) provided on the second plate (231) and provided in close contact with the central axis (32) so that the central axis (32) seated on the second rotating rollers (232) does not detach during the rotation process.

[0037] The second plate (231), like the first plate (131) described above, allows the second rotating roller (232) and the second anti-detachment guard (233) to be installed on the second support (22). The second rotating roller (232) is positioned so that two roller axes are positioned parallel to each other, and the central axis (32) is rotatably seated on the upper part of these two rollers. That is, when the central axis (32) is rotated, the rollers on both sides on which the central axis (32) is seated rotate freely, so that the cable drum (60) can be stably rotated in both directions.

[0038] The aforementioned second anti-detachment guard (233), like the aforementioned first anti-detachment guard (133), serves to prevent the central axis (32), which is positioned on the second rotating roller (232), from detaching during rotation. It may be in the form of an elastic band or a metal piece having a curvature corresponding to the central axis (32). It is preferable that this second anti-detachment guard (233) be coated with a material having a lubricating function so that no frictional force is generated when the central axis (32) rotates.

[0040] Meanwhile, a rotating shaft portion (30) is fixedly installed in the axial direction on each side of the cable drum (60). This rotating shaft portion (30) serves to allow the cable drum to be rotatably seated on the aforementioned first rotating roller (132) and second rotating roller (232). To this end, a central shaft (32) is formed protruding from the side of the rotating shaft portion (30) so as to be rotatably seated on the first roller unit (13) and the second roller unit (23).

[0041] The rotating shaft portion (30) includes a disc (31) fixed to both sides of the cable drum (60) and a central shaft (32) formed in a cylindrical shape and provided through the center of the disc (31), with one side inserted into the cable drum (60) and the other side resting on the aforementioned first rotating roller (132) and second rotating roller (232), and having a fastening groove (321) formed at the end of the other side so as to be detachably fastened to a drive shaft (43) to be described later.

[0042] That is, the cable drum (60) is in a circular state and does not have protrusions formed at both ends to be seated on the first rotating roller (132) and the second rotating roller (232). Therefore, fixed protrusions that can be seated on the first rotating roller (132) and the second rotating roller (232) are formed on both sides of the cable drum (60) by installing a rotating shaft part (30). It is preferable that the rotating shaft portion (30) has a disc (31) that is firmly bolted to both sides of the cable drum (60), and that one end inserted into the cable drum (60) is formed to a size corresponding to the inner diameter of the through hole formed on both sides of the cable drum (60), and the other end seated on the first rotating roller (132) and the second rotating roller (232) is formed to a size that can be wrapped in close contact with the first anti-detachment protector (133) and the second anti-detachment protector (233).

[0044] And a driving unit (40) is disposed on one side of the first support member (10) or the second support member (20) described above. This driving unit (40) receives rotational force supplied from the motor unit (50), which will be described later, and transmits it to the central axis (32), thereby enabling the cable drum (60) to rotate.

[0045] This drive unit (40) is provided with a third base (41) on its bottom, a third support (42) installed vertically in the upper center, and a drive shaft (43) connected in the same direction as the aforementioned central axis (32) on the upper side.

[0046] As described above, the third base (41) is fixed to the second base (21) by the second fixed plate (221), which is the case where the driving unit (40) is positioned on one side of the second support unit (20), and when the driving unit (40) is positioned on one side of the first support unit (10), the third base (41) is fixed by the first base (11) and the second fixed plate (221).

[0047] The aforementioned drive shaft (43) is directly connected to the central shaft (32) and serves to transmit the rotational force of the motor unit (50), which will be described later, to the central shaft (32). To this end, the drive shaft (43) is positioned horizontally on the upper part of the third support (42) in a rotatable state. At one end thereis, a fastening projection (431) is formed to be detachably connected to the fastening groove (321) of the aforementioned central shaft (32), and the fastening projection (431) is inserted into the fastening groove (321) and is detachably fixed by a fastening pin. At the other end of the drive shaft (43), a circular rotating gear (432) is provided to receive rotational force from the motor unit (50), which will be described later.

[0049] The aforementioned third base (41) is equipped with a motor unit (50) that can be operated. This motor unit (50) is connected to the drive shaft (43) of the aforementioned drive unit (40) and transmits rotational force to the drive shaft (43) depending on whether it is operated, and rotates the first roller unit (13) or the second roller unit (23) connected to the drive shaft (43) to cause the cable drum (60) to rotate.

[0050] This motor unit (50) is drivably installed on the third base (41) and includes a motor (51) with a reduction gear integrated therein, and a belt (52) that is integrally connected between the reduction gear and the rotating gear (432) integrated therein to transmit the rotational force generated by the motor (51) to the rotating gear (432). That is, when the motor (51) is operated, the drive shaft (43) connected to the reduction gear side of the motor (51) by the belt (52) rotates, the center shaft (32) connected to the drive shaft (43) rotates, and the cable drum (60) can be rotated.

[0051] At this time, although not shown, a controller capable of controlling the rotation direction and rotation speed of the motor (51) is provided on one side of the motor part (50), and a power supply unit necessary for the operation of the motor (51) is also provided.

[0054] Hereinafter, the overall method of use of the cable drum winding device (1) according to a preferred embodiment of the disclosed content will be explained in detail with reference to FIG. 4.

[0056] First, a rotating shaft portion (30) is installed on both sides of the cable drum (60). At this time, the disc (31) is bolted to both sides of the cable drum (60), and one end of the central shaft (32) is inserted into the cable drum (60) while the other end protrudes outward.

[0057] Then, the cable drum (60) with the rotating shaft (30) installed is positioned on the first support (10) and the second support (20) arranged on both sides. One of the central shafts (32) protruding from both sides of the cable drum (60) is placed on the first rotating roller (132), and the other is placed on the second rotating roller (232). The first anti-detachment guard (133) and the second anti-detachment guard (233) are each closely fixed to the upper parts of the central shafts (32) on both sides. In this way, the cable drum (60) is positioned on the first support (10) and the second support (20) in a state spaced apart from the ground.

[0058] Then, the drive shaft (43) fastening projection (431) of the third support member positioned on one side of the second support member (20) and the center shaft (32) fastening groove (321) seated on the second rotating roller (232) are engaged with each other and then fixedly fastened using a fastening pin.

[0059] Then, when the motor (51) of the motor unit (50) is operated, the drive shaft (43) connected to the reduction gear side of the motor (51) by the belt (52) rotates, the center shaft (32) connected to the drive shaft (43) rotates, and the cable drum (60) rotates. At this time, depending on the direction of rotation, the cable may be wound or unwound.

[0060] When the winding or unwinding operation of the cable is finished, the drive shaft (43) that was connected to the central shaft (32) is detached, and the first anti-detachment guard (133) and the second anti-detachment guard (233) that were fixed in close contact to the upper part of both central shafts (32) are each released. Then, the cable drum (60) is lifted onto the first support member (10) and the second support member (20) for transport and storage.

[0063] According to the winding device for a cable drum as described above, a cable drum equipped with rotating shafts on both sides is rotatably seated on a first support and a second support, and by transmitting the driving force of a motor unit to the seated cable drum through a driving unit, the winding or unwinding of a communication cable can be performed quickly and safely with minimal labor.
